Ok, I know this from experience, whenever my boyfriend asks me to give him a back rub, I get behind him and I firmly start going at his shoulderblades making his head come back to my shoulder while my head is at one side..

While doing that, lightly wiht a warm sensation blow in his ear and give it a lil nibble, BUT BE VERY GENTAL!

If you blow too hard, its a turn off

and if you bit too hard that could be a turn off..

(before you blow or nibble on his ear make sure he likes it before hand.. TRUST ME it works!!!)
